Abstract: APPARATUS AND METHOD FOR PRODUCING SPHERICAL ARTICLES               Abstract of the Disclosure An apparatus and method for compressing powder material into at least partially spherical articles, comprising a die and upper and lower reciprocally movable punches.  The die has a center bore through which the lower punch is reciprocable.  The wall at the upper part of the die bore is enlarged to form a spherical zone portion of a hemispherical cavity.  The end face of the lower punch has a concave shape to form a segment of the hemispherical cavity when the face of the lower punch is flush with the die cavity wall. The lower face of the upper punch de-fines a hemispherical cavity which mates with the hemispherical cavity of the die.  In operation, the bore and die cavity are charged with powder material and the upper punch is brought into engagement with the die.  A compaction stroke by the lower punch then forces the powder material into the spherical cavity.  The upper punch is then withdrawn and the compacted spherical article is removed from the die.  Alternatively, the end face of the lower punch may be flat, convex, or any other appropriate shape to compact partially spherical articles.  A portion of the mold-ing cavity may be coated with an elastomeric material.

Abstract: RECORDING AND REPRODUCING APPARATUS      FOR COLOR VIDEO SIGNALS                     ABSTRACT OF THE DISCLOSURE            A recording and reproducing apparatus for color video signals, in which the color video signal is recorded, the chroma signal of the color video signal is frequency-con-verted by a carrier from an oscillator whose frequency is fa = [(455/2) + {(2n + 1)/4}fH so that the chroma signal is compressed to a very low frequency band with the sidebands of the chroma signal being interleaved with each other.  The thus compressed signal is frequency-modulated and recorded, and are then reproduced and demodulated.  The demodulated signal is balance-modulated and passed through a comb-filter to reproduce the chroma signal.  Since the chroma signal is frequency-modu-lated before the recording, possible fluctuation of the signal level due to the recording and reproducing means does not affect the resulting reproduced chroma signal.  Also, since the chroma signal is compressed to a very low frequency band, a time base error (jitters) which might possibly occur in the resulting reproduced chroma signal due e.g. to a fluctation of the mechanical operation, such as magnetic tape movement, of the recording and reproducing means can be minimized.

Abstract: PRODUCTION OF IMPROVED POLYESTER FILAMENTS    OF HIGH STRENGTH POSSESSING AN UNUSUALLY      STABLE INTERNAL STRUCTURE              ABSTRACT OF THE DISCLOSURE An improved process is provided for the formation of a high perform-ance polyester (at least 85 mol percent polyethylene terephthalate) multi-filament yarn.  The product possesses a high strength (at least 7.5 grams per denier) and an unusually stable internal structure which renders it par-ticularly suited for use in industrial applications at elevated temperatures. The filaments are melt spun and uniformly quenched under relatively high stress conditions (as described) to yield an as-spun filamentary material of relatively high birefringence (+9 x 10-3 to +70 x 10-3) which is passed in-line from the quench zone to a first draw zone where it is drawn at a draw ratio of 1.01:1 to 3.0:1, and subsequently is drawn (as described) to achieve at least 85 percent of the maximum draw ratio of the as-spun filamentary mate-rial.  The resulting filamentary material exhibits unusually low shrinkage and hysteresis characteristics (i.e. work loss characteristics) as well as the high strength characteristics.  Accordingly, when utilized in the forma-tion of a tire cord and embedded in a rubber matrix a highly stable tire may be formed which exhibits a significantly lesser heat generation upon flexing.

Abstract: ABSTRACT OF THE DISCLOSURE A method for coating an electroconductive article such as a continuous length of flat metal sheet is disclosed.  The method of the invention involves passing the electroconductive article into an aqueous electrodeposition bath which contains as the electrocoating vehicle a water-soluble resinous coating material in combination with a water-insoluble emulsified resinous material. The vehicle is electrodeposited on said metal sheet to form a primer coating as the electroconductive article passes through the electrodeposition bath. A top coat is applied to said primer without having previously baked the primer, and the topcoated metal is then passed to a baking station where the top coat and primer coat are baked simultaneously.  The combination of solubilized and emulsified resinous materials offers a number of processing advantages.  For example, the electrodeposition bath can be operated at higher temperatures than are normally associated with electrodeposition and since only one baking station is needed, equipment and fuel costs are minimized.
